Research on cross-network cooperative development mode based on 3D model

In order to solve the problems in the development mode based on two dimensional drawings, it is difficult to express the design and processing intention of complex parts, and it is impossible to realize production and processing simulation and automatic quality inspection. Based on MBD (Model Based Definition) technology, this paper expounds the whole process digital development mode and management method. Firstly, the model-based overall architecture is described from the development mode and management mode. Then, around the key business scenarios such as structural design, process design, CNC machining and quality inspection, the role and ability of MBD technology in each link are discussed. Finally, by expounding the digital transformation brought by MBD technology to enterprises, it is possible to introduce digital twin technology. Through the bidirectional mapping of physical test questions and digital models, the status monitoring and fault analysis of physical products are realized.
